3 Claims. (Cl. 25-131) This invention relates to Wall forms andparticularly such as are used for pouring concrete, cement and the likefor architectural purposes.

Presently known forms are either fabricated at the building site orconsist of a large number of prefabricated elements which are securedtogether to receive the concrete or cement mix. All of these formsrequire nailing and fastening means which consume time and render thelumber employed in the construction of the forms useless for subsequentpurposes.

Accordingly, it is an object of the present invention, to provide a wallform system which will not require the use of nails.

Another object of the present invention is to provide a wall form systemrequiring a minimum number of elements for form erection.

Still another object of the present invention is to provide awall formsystem which may be erected with relatively unskilled labor.

' A further object of the present invention is to provide a Wall formsystem which will effect a substantial saving in materials and labor.

An object of the present invention is to provide a wall form system inwhich all of the lumber is of standard and therefore easily obtainabledimensions.

A feature of the present invention is its round barshaped tie which maybe inserted from either side of the wall form system.

Another feature of the present invention is its waler hook constructionwhich may be used to secure adjacent panels together and also supportwalers.

Still another feature of the present invention is its spacer-wedgemember for fastening the panels to the ties.

The invention consists of the construction, combination and arrangementof parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming a part hereof, is illustrated oneform of embodiment of the invention, in which drawings similar referencecharacters designate corresponding parts, and in which:

FIGURE 6 is a view in front elevation showing the manner in whichpanelsof different sizes can be secured together. I

FIGURE 7 is a view in perspective of a tie used in the present wall formsystem.

FIGURE 8 is a view in perspective taken from the panel side thereofshowing a combined spacer wedge and a plate and waler hook assembly.

Referring to the drawings and particularly to FIGURE 1, 10 indicates awall form system comprising spaced panel members 11 which may be made ofplywood, hardboard, or some suitable material having an inner cenitcdStates atent 0 ment pouring face. Vertical studs 12 support the outsidesurface of the panel members 11. Horizontal walers 13 which serve tostrengthen and align the studs 12 are secured to the wall form system aswill be hereinafter more fully described. The studs 12 and walers 13 mayconsist of readily available two by fours as illustrated. If additionalwaler strength is desired, two by sixes may be substituted at this pointin the wall form system.

The wooden members of the wall form system are fastened together byinterlocking accessories generally indicated at 14. The accessories 14include ties 15 (best shown in FIGURE 7) combined spacer wedge members16 and waler hooks 17.

The ties 15, as shown in FIG. 7, consist of an elongated bar 18 whichmay be made of round stock. Weakening or break back recesses 19 are madein the tie 15 at points spaced from each end thereof, so that they willlie within the poured structure as illustrated in FIGURES l and -5; -Thebreak back recesses 19 have sutficient strength to support the formsduring the pouring operation, but will break after the wall of concretehas hardened if the end of the tie 15 is twisted in the mannerhereinafter more fully described.

Wedge engaging recesses 20 are formed at each end of the tie 15. Therecesses 20 have shoulders 21 at each end thereof to receive the spacerWedge member. The recesses 19, 20 may be formed by means of suitabledies which swage the metal from the bar stock to form a unitary tiestructure.

The ties 15 may be slid between the spaced panel members 11 throughaccurately spaced holes 22 which are provided in each of the panels 11for this purpose. The ties 15 will project a short distance beyond thepanels 11 as shown in FIGURES 2, 4 and 5. The projecting ends of theties 15, as shown in FIGURE 2, are adapted to receive thereon thecombined spacer wedge member 16.

The spacer wedge 16 is formed with a fiat spacer plate 23 which bearsagainst the outer face of the panel 11 and has a slotted opening 24therein, as best shown in FIG- URE 8. The slotted opening 24 slips overthe recess 20 at the end of the tie, and bears against the innershoulder 21 of said recess. An outwardly bent flange 23A is provided onthe plate 23 and is used in breaking back the ties. The Workman canstrike the flange 23A with a bar or hammer to twist and break the ties15 at the weakening notches 19. A wedge member 25 is welded to the frontof the plate 23. The wedge 25 is provided with a keyhole slot 26 on theinclined plane 27 thereof, which slot engages the tie recess 20 andbears against the outer shoulder 21 of the said recess. With the spacerwedge member secured to the tie, the tie can not be pulled into thespace between the panels 11 by the tightening of the wedge 16 on theopposite side of the spaced panel assembly. The distances between thepanels 11 is thus established and maintained from the outside of thewall formsystem. Presently used interior form panel spacer members are,therefore, not required. The spacer wedge 16 is provided with a nutmember 28, which is carried in the upper portion thereof, as shown inFIGURES 2 and 5. The nut member 28 is in register with an opening 29 inthe inclined plane 27. A waler bolt 30 is received within the opening 29and threaded into thenut 28. The outer end of the waler bolt 30 isprovided with a head 31 for'tightening the bolt and preventing the walerhook 17, which is slidably carried on the bolt 30, from leaving thebolt. The waler hook 17, bolt 30, and spacer wedge 16 form a combinedelement which can be hand-led as one fastening accessory during theerection of the form.

As shown in FIGURES 2 and 3, the waler hook 17 Patented Nov. 7, .1961,

is provided with spaced tapered slots 32. The slots 32 are used whereadjacent panels 1 1 are to be held in abutting relationship. For thispurpose, the panels 11 are provided with flat-headed bolts 33, commonlyknown as plywood bolts, which are inserted in holes within the panels 11at suitable intervals. The waler plates 17 may be removed from theirwedge assembly, a bolt 30 slipped through the central opening 35 thereinand the tapered slots 32 slipped over the plywood bolts 33 until theadjacent panels 11 are forced tightly together. The waler plate 17 ispreferably formed with a concave portion 36 about the opening 35 toreceive the bolt head 31 and permit the plate to lie flush against thepanel 11. A second waler plate 17 is then slipped over the extending endof the bolt 30, as shown in FIGURE 3 and a spacer wedge 25, on the nut28, used to lock the walers 13 tightly against the studs 12. When thestuds 12 and walers 13 are slipped into place, the panels 11 are securedtogether and aligned without the need of further nailing.

Referring to FIGURE 6, it will be seen how panels 11 of different sizesmay be employed to achieve forms of any desired height. In FIGURE 6,panels 11 having standard four by eight foot size are combined withpanels having 2 x 8 and 1 x 8 dimensions to get desired wall heights.The panels 11 have drilled holes 22 to receive the ties 15 and plywoodbolts 33.

When it is desired to erect a wall form in accordance with the presentsystem, panel members 11 are placed upon suitable footings (not shown)and secured together by means of the waler hooks 17, as shown in FIGURES3 and 6.

Thereafter, the top waler members 13 are laid upon the waler bolts 30.The studs 12 may then be slipped between the top walers 13 and the panel11, and rotated into the positions shown in FIGURES l, 2 and 3. Thebottom waler members 13 are then slid into place on top of the flanges34 of the waler hook 17. The waler bolt 30 may be tightened by means ofthe bolt head 31 to lock the wood members together. Ties 15 can then beinserted through the openings 22 in the panels 11 and secured on eachend, as shown in FIGURE 5, by the spacer wedge members 16. Additionalwalers hooks 17 are secured to the waler bolts 30 and grasp within theirflanges 34 the walers 13. When the bolts 30 are tightened, the entireassembly will be rigidly locked together ready for pouring. Bracesupporting angles 37 may be combined with the waler hooks 17, as shownin FIG- URE where desired.

After the concrete has hardened between the forms, the bolts 30 areloosened until the walers 13 can be slipped out of the waler hooks 17.The studs 12 will thereupon fall away from the panels 11. The spacerwedge members may then be used as a wrench to break back the ties 15. Asthe spacer wedges 16 are twisted, they will cause the ties 15 to breakat the weakening notches 19 which are well within the poured panel. Theresulting small hole may be finished with cement to provide a smoothunbroken wall surface.

When the ties 15 are broken, the panels 11 will fall free of the pouredwall and may be used again. Since there are no nails used in theerection or stripping of the form, the lumber will remain useable over alarge'number of operations, and the supporting studs and walers may evenfind their way into framing and other architectural uses in theconstruction or" the building.

It will be apparent that very little of the tie metal is wasted, andthat only a small portion of the tie need project beyond the wall formin the present assembly.

in erecting the present forms, workmen need only carry ties, waler plateand bolt assemblies, and the spaced wedge-waler hook assembly.Miscellaneous hardware is thus reduced to a minimum, and the only toolnecessary to erect or strip a form will be a hammer, which is used todrive the various elements into engagement with the ties or plywoodbolts and break back the ties in stripping. Studs 12 of any availablelength may be used, and variations in lumber thicknesses can be taken upby means of the bolt 30.

Where it is desired to crane handle a large section of forms withoutcompletely disassembling them it is possible to remove the waler hooksand bolts from the spacer wedges 25. The wedges 25 can then be struck tobreak back the ties 15. The remaining hooks, bolts, studs, walers andhardware in the forms will hold the assembly rigidly together so thatthey can be moved as a unit. A great saving in erecting costs is thuspossible. Once set up at the next pouring operation it is merelynecessary to push new ties through the panels 11 and secure them inplace as hereinabove set forth.

From the foregoing it will be apparent that there has been provided anextremely simple nail-free wall form system which is economical ofmaterials, reuseable and easily erected and stripped, without the needfor complicated tools or operations.

Having thus fully described the invention What is claimed as new anddesired to be secured by Letters Patent of the United States is:

l. A spacer wedge member for securing panels into a rigid wall formassembly comprising a wedge shaped member, a keyhole slot in said wedge,a spacing plate on said wedge, an elongated slot on said plate, saidslots being in register and a bolt receiving member carried by saidwedge.
